The actor lent his voice this week for an online trailer that will be used to promote “Head Smash,” a joint property that Vlad Yudin, of the Vladar Co., and Arcana’s VP of publishing Erik Hendrix co-wrote together.

The full version of the book will be sold at San Diego Comic-Con this week, after debuting the first 10 pages at New York’s Comic Con last October. Paxton also will participate on Arcana’s “Head Smash’ Comic-Con panel, July 19.

A limited-edition cover of the book will be available at Comic-Con designed by art director Joe Perez, behind Kanye West’s album covers.

“Head Smash” is a sci-fi thriller that revolves around a loyal soldier of the brutal crime syndicate Horde, who armed with a serum that gives him superhuman strength, seeks revenge against the group that betrays him and takes his family. Book hits bookstores July 31.

Yudin and his partner Edwin Mejia have been using the fanfest circuit to launch a grassroots campaign to introduce the title and characters. They felt they had to turn to Comic-Cons across the country in order to emerge from the shadows of larger publishers like DC and Marvel to build a following for their indie title.

Yudin is also producing and adapting a screenplay based on “Head Smash” that “The Twilight Saga” producers Mark Morgan and Imprint Entertainment-chief Michael Becker have come on board to produce, along with Arcana’s CEO Sean Patrick O’Reilly.

Since launching their shingle in 2008, Yudin has written, directed and produced the documentary “Big Pun: The Legacy” about the late rapper Christopher Lee Rios, and the dramedy “Last Day of Summer,” starring DJ Qualls and actress Nikki Reed. His documentary “Generation Iron,” that chroniclees competitors for the Mr. Olympia title, is out in September, narrated by Mickey Rourke.

“Seven Holes of Air,” written by John J. McLaughlin, with art by Mick Reinman, was first published as a digital graphic novel. Arcana is debuting the print version at Comic-Con.

Project, which features homages to Spaghetti Westerns, began as a film script Paxton was eyeing to star in before he pitched the idea as a graphic novel. Scribe and artist are both working on the “Kung Fu” adaptation Paxton is helming.

Paxton will next be seen in Universal’s actioner “2 Guns,” with Mark Wahlberg and Denzel Washington; Warner Bros.’ “All You Need is Kill,” with Tom Cruise; and Disney’s baseball pic “Million Dollar Arm.”
